Application led September 23, 1908. Serial No. 454,395.

To all whom it may concern.'

Bc it known that I, JAMES EDWIN Giens, a citizen of the United States,residing at Huntington, in the county of Cabell and State of llllestVirginia, have invented. a new and useful Sash-Locking Device, of whichthe following is a specification.

T he present invention relates to means for locking the sashes of awindow against movement and in different adjusted positions.

The primarg.-Y object of the present invention is to provide a simpleand effective structure of the character set forth, that can be readilyapplied to a window frame without any great alteration of the same, isinvisible from the exterior the window and cannot be operated from theoutside.

The preferred form of construction is illustrated in the accompanyingwherein Figure 1 is a view in elevation of the inner face of a portionof a window frame, with the sashes removed and slimving the loclr inelevation. Fig. 2 is a sectional view on the line 2-2 of Fig. l. Fig. 3is a vertical sectional view on the line 3 3 of Fig. 1. Fig. 4 is a rearelevation of the locking device complete. Fig. 5 is a detail sectionalvienV on the line 5--5 of Fig. 4. Fig. 6 is a detail perspective view ofthe sash holding clement.

Similar reference numerals designate corresponding parts in all thofigures of the drawings In the embodiment illustrated, the window frame7 may be of any well known form, and contains the usual upper and lowersashes 8 separated by a parting strip 9 that is seated in a groove 1U. Asoclret 11 is formed in the frame and intersects thogroove, being widerthan said groove, as clearly illustrated in Ilig. 1. Below this socket,the opposite side walls of the groove are provided with recessed seats1.2. A dovetailed groove 13 is formed in the frame transversely of thegroove 10, and extends through the inner side of the frame below theinner sash retaining strip 14. It will be observed particularly byreference to Figs. 2 and 3 that the edges of the sashes adjacent to thewall of the frame constructed as abovel described, have sockets or seats15.

A sash holding device is provided that preferably consists of a strip ofthin highly tempered steel doubled at its central pordrawinga tion andformed into a comparatively large ring 16 that lits snugly into thesocket 11, and consequently extends entirely across the groove 10. Thering is maintained in the socket by means of nails 17, or other suitablefasteners extending over said ring.

`Depending' divcrgently disposed arms 18 extend from the ring and arelocated. in the groove 10. The lower free ends of said arms areoppositely outturned and bifurcated to produce sets of lips or teeth 19and 20, the latter being preferably longer than the former, as shown inYEig. 6. The lips or teeth 1Q engaged in the seats 12, while the lips orteeth 20, which are carried by projecting portions 21 on the arms 18,are arranged to engage in the different seats 15 of the sashes. Theparting strip 9 is cut away at the place occupied by the sash lockingdevice in order that it will not in any manner interfere with theoperation thereof, as here inafter described.

A channeled actuating slide 22 is employed having its flanges 23 liaredand operating in the dovetailed groove 13. This device or slide 22 hasthe upper portion at its inner end cnt away, as shown at 24, producing apair of shoulders 25 that bear against the lower ends of the arms 18. Itwill thus be evident that upon the outward movement of said slide, theinner arm will be moved inwardly so as to carry its tooth 2O out ofengagement with the lower sash, while on the inward movement of theslide, the tooth 2O ofthe outer arm will be carried out of engagementwith the upper sash. `Under normal conditions, however, the arms 18 arespread apart, so that both the teeth are in engagement with theirrespective sashes.

Fulcrumed between its ends on the slide 22 and located in the channelthereof is a holding lever 25, the outer end of which is provided with alooped portion 26 forming a linger piece, the inner end being upturnedas shown at 27 and adapted to engage between the lower ends ofthe arms18 to prevent their opposite movements toward each other. A spring 2S ofany suitable construction is preferably employed to bear against thelever 25a so as to urge the end 27 between the arms.

ln applying this device to a window frame, it is only necessary to cutout the socket 11, the seats 12, the groove 13 and cut away the partingstrip, whereupon the elements 'of the locking device can be readilyintroduced into place and secured, the only securing means necessarybeing the nails or pins 17. When the teeth 2() are in engagement withboth sashes, said sashes are securely held against movement. To unlockeither, it is only necessary to raise the finger piece 26 and move theslide either in or out, whereupon one of the teeth 2O will be disengagedfrom the sash and its movement will be permitted. When relocked,however, the spring 28 will act to automatically throw the lever 25Lqtoa position with the end 27 between the arms. This feature is ofconsiderable importance, as it prevents the retaining strip for theouter sash being pried up, and an instrument introduced beneath it toforce the tooth 20 rearwardly, and thus permit the lowering of the sash.rlhe particular construction and arrangement oi the locking element isalso important. By having a large ring 16, there is no danger of thedevice rocking on an axis disposed longitudinally of the groove 10, andthis ring engaging in the opposite walls ofthe groove, constitutesholding means that prevents the longitudinal movement of the element.The teeth 19 also prevent such longitudinal movement, and furthermoreact as positioning devices inasmuch as both cannot be disengaged fromtheir seats at the same time. By having the ring 11 uppermost and thelocking element disposed adj acent to the joint between the upper andlower s'ashes when closed, such element is always covered and cannot beseen from the outside of the window. The actuating device also has itsadvantages. In the first place, it is eilfectively retained in positionbecause of its dovetailed formation, and the lever being located in thechannel, is entirely out of the way, and a smooth outer surface isprovided that will not interfere with the free movement of the sashthereover.

From the foregoing, it is thought that the construction, operation andmany advantages of the herein described invention will be apparent tothose skilled in the art without further description, and it will beunderstood that various changes in the size, shape, proportion and minordetails of construction may be resorted to without departing from` thespirit or sacrificing any of the advantages of the invention.
